navigation component with navigation view android
问题
我正试图使用导航组件进行工作。<br>
目前我有带有菜单的导航视图。<br>
我在导航视图中实现了onNavigationItemSelected，并通过item.getItemId()来检测点击，
当点击特定项目时，它会执行一些不是导航到片段的操作。例如：
switch (item.getItemId()) {
case R.id.nav_share:
Intent sharingIntent = new Intent(android.content.Intent.ACTION_SEND);
sharingIntent.setType("text/plain");
String shareBody = "与朋友一起保持关注，bla bla bla，我们可以将应用程序网址放在Google Play中，" +
"如果我们不会是SDK的话";
sharingIntent.putExtra(android.content.Intent.EXTRA_TEXT, shareBody);
startActivity(Intent.createChooser(sharingIntent, "通过以下方式分享"));
break;
case R.id.nav_disconnect_user:
FirebaseAuth.getInstance().signOut();
break;
}
我如何使用导航组件实现这一点？
谢谢！

currently I have navigation view with menu. <br>
I implement onNavigationItemSelected in navigation view and detect click by
item.getItemId() when there is clicks on specific items, it do something that not navigate to fragment. for example:
switch (item.getItemId()) {
case R.id.nav_share:
Intent sharingIntent = new Intent(android.content.Intent.ACTION_SEND);
sharingIntent.setType("text/plain");
String shareBody = "shae StayTuned with friends bla bla bla and we can put app url in the google play " +
"if we don't will be sdk";
sharingIntent.putExtra(android.content.Intent.EXTRA_TEXT, shareBody);
startActivity(Intent.createChooser(sharingIntent, "Share via"));
break;
case R.id.nav_disconnect_user:
FirebaseAuth.getInstance().signOut();
break;
}
how I can achieve that with navigation component?
thanks!

Here's the translated content:
使用导航组件时，您无需手动实现OnNavigationItemSelectedListener，因为setupWithNavController()方法会将目标与在导航图和菜单项之间匹配的android:id连接起来。
如果您使用自定义的NavigationItemSelectedListener，则会删除原始的监听器。在这种情况下，您需要调用NavigationUI.onNavDestinationSelected()来触发默认行为。
navigationView.setNavigationItemSelectedListener {
when (it.itemId) {
R.id.R.id.nav_share -> {
// 处理点击事件
true
}
}
// 调用原始监听器
NavigationUI.onNavDestinationSelected(it, navController)
drawerLayout.closeDrawer(GravityCompat.START)
true
}
英文:
With the navigation component you don't need to manually implement a OnNavigationItemSelectedListener since the setupWithNavController() method connects destinations to menu items matching the android:id between your navigation graph and menu items.
If you use a custom NavigationItemSelectedListener you are removing the original listener. In this case you have to call NavigationUI.onNavDestinationSelected() to trigger the default behavior.
navigationView.setNavigationItemSelectedListener {
when (it.itemId) {
R.id.R.id.nav_share -> {
// handle click
true
}
}
//Call the original listener
NavigationUI.onNavDestinationSelected(it, navController)
drawerLayout.closeDrawer(GravityCompat.START)
true
}
